Text Box Glow State Change Hover

Good morning. I can't figure out why adding the shape effect "glow" isn't working for my text boxes. I want to add a hover state to each of the index options (Work/Life/Zeta Balance, Visiting Your Chapters, etc.) but even when I try to add it to the actual text box it doesn't show up, and it's no different when I add it as a hover state. Help!

I'm guessing that it is working, but the glow is pretty hard to see, even for people with good eyes, and even on contrasting backgrounds in good light. I usually choose an alternative that I know won't be missed even under marginal conditions.
